Non-refillable bottle.



TOKUTARO NISHIDA, OF SEATTLE, WASHINGTON.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented June 17, 1913.

Application filed March 25, 1912. Serial No. 685,994.

To all whom it may concern Be it known that I, TOKUTARO NISHIDA,

' a subject of the Emperor of Japan, and a resident of the city ofSeattle, in the county of King and State of lVashington, have inventedcertain new and useful Improvements in Non-Refillable Bottles, of whichthe following is a specification.

My invention has for one of its objects to provide a simplified andimproved construction of the above type, which, while being capable ofready removal by authorized parties, will safe-guard the latter as wellas the trade against adulteration or substitution with respect to thecontents of the bottle.

A further object resides in the provision of novel valve securingmechanism.

Other objects will be set forth as my description progresses and thosefeatures of construction, arrangements and combinations of parts onwhich I desire protection, succinctly defined in my annexed claim.

Referring to the accompanying drawing wherein like numerals of referenceindicate like parts throughout: Figure 1 is a vertical section of myattachment applied as in use, the valve controlling device beingadjusted to secure the valve closed. Fig. 2 is an elevation of theattachment and the upper end portion or neck of the bottle, the casingof said attachment being broken away and illustrating the valvecontrolling device in its releasing position, and Fig. 3 is a crosssectional view taken on line 33 of Fig. 1. Y

My invention comprises a casing 1 having its upper end portionexternally screw threaded and provided with spaced apertures 2 which arenormally closed by an annular flange 3 having threaded engagement withthe said threaded portion of the casing. Flange 3 depends from arotatable casing-closure 3, constituting a member for advancing andretracting a valve controlling device 4:, which latter is convenientlyin the form of a stem fixed to said closure 3 and projecting through aperforated guard 5, fixed to said casing above valve 6 and limitingupward movement of the latter (see Fig. 2), as in my Patent 1,012,095.The lower end portion of stem t is provided with a shoulder 7 whichduring movement of said stem to its releasing position engages guard 5to limit upward movement of closure 3 immediately after flange 3 of thelatter has uncovered apertures 2, and thereby prevent removal of theclosure from casing 1, as shown in Fig. 2. Valve 6 which is adapted toseat flatly upon the upper end of the bottle neck, is provided with afacing 6 of suitable yielding material, as for example, rubber or cork,and with a lug 6 connected by a pivot pin 8 with lugs 9 of the casing,the aperture of lug 6 being elongated to permit of slight play of thevalve which is desirable in obtaining a firm seating of the latter onthe bottle, as is apparent.

Reference numeral 10 indicates the bottle on the neck 10 of which casing1 is mounted, the lower end portion of said casing receiving the bottleneck 10 and having screwthreaded engagement therewith, as shown.

Casing 1 can be sealed against removal by unscrupulous persons, in anydesired mannen. A convenient method however, consists in applying thesealing material, as 11, to the bottle neck and over the lower edgeport-ion of the casing which latter may be cutout, as at 12, forreception of a portion of the sealing material to obtain a more perfectseal. To close apertures 2one of which is designed to serve as an outletport and the other as a vent, closure 3 is screwed downwardly and suchmovement adjusts device 4: to firmly press and hold valve 6 on the upperedge of the bottle neck 10'.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent of the United States of America, is

In combination with a bottle, a casing on the neck of said bottle, saidcasing having its outer end open and formed in its side wall with adischarge opening, the outer end portion of said casing beingscrew-threaded, a valve in said casing, a guard in said casing abovesaid valve, said guard consisting of a perforated plate, a ventingremoval of the latter from the caselesure for the open outer end of saidcasing, for the purpose specified.
